Kenmore side by side refrigerator

I did changed the capacitor.These are the two parts that i replaced:
1 of AP4315853 (5304464438) - CAPACITOR
1 of AP4367355 (5304468029) - RELAY AND PLUG KIT
Its good to know that Frigidaire made that refrigerator.
Is there any way to make sure that the faulty component is the compressor, before I call those guys?
Thank You
